Abstract

PURPOSE:To make it possible to suppress quickly the steam pressure variation in a boiler drum by providing a temperature target value control device which makes control, dependent on steam pressure, of a temperature target value in the control action by means of a heat recovery and air supply control device for the temperature of the fluidized bed in a combustion compartment. CONSTITUTION:An operation output signal MV01 which brings the steam pressure signal PV01 from a manometer 20b to balancing with a pressure target value signal SV01 is supplied to a combustible matter supply device 14 to make a control dependent on steam pressure of the amount of combustible matter supply. Further, a temperature regulator 33 supplies an operation output signal MV02 which brings the temperature signal PV02 from a temperature sensor 3a to balancing with a temperature target value signal SV02 to a flow rate regulator 34 as a target value signal SV03, and said flow rate regulator 34 supplies an operation output signal MV03 which brings a flow rate signal PV03 from a flow rate meter 9b to balancing with the target value signal SV03 to a control valve 9b and changes the amount of air supply to a heat recovery compartment 4 and makes a control dependent on temperature of the recovered heat quantity from the heat recovery compartment 4 to a boiler drum 17. Those control actions are interlinked in connection with the target value signal SV02 of the temperature regulator 33.
